One of 16 AN/FRD-10 high-frequency direction-finding arrays built by US and Canada in the 1960s and 1970s. These sixteen stations, along with a number of Pusher HF/DF arrays, comprised the US Naval Security Group's BULLSEYE HFDF net. Pushers was simply the name given to simpler CDAAs.

The arrays operated in the range of 2 to 32 MHz. Their function was to detect, monitor, and plot the location of Soviet submarines and other radio emitters in the Atlantic and Pacific oceans. The largest array was some 260 m in diameter, 36 m high, and sat on a ground plane of 390 m diameter, with a two storey building at its centre, housing the main equipment and operators.
